彩电中能有各种色彩的图象,是利用红、绿、蓝三种基本色先按不同方式复合而成的.初二物理课本中作了介绍,并把这三种色光叫做彩电的三原色.为了说明彩电中各种色彩是由这三原色复合而成的,可以做如下的实验:接通彩电的电源,电视机的屏幕上呈现彩色的图象.在银屏上洒一滴水,由于重力作用,水滴在银屏上形成一个“三棱镜”.水滴所在位置的色光通过这一“三棱镜”时,就会发生
Color TV can have a variety of colors of the image, is the use of red, green, blue three basic colors in accordance with the first compound in different ways. In the second physics textbook was introduced, and the three colors called color TV’s three primary colors In order to illustrate that various colors in a color TV are compounded by these three primary colors, the following experiment can be done: Turn on the power of the color TV, a colored image is displayed on the screen of the TV. Sprinkle a drop of water on the screen, due to gravity The water droplets form a “triangular prism” on the silver screen. When the color of the water droplets passes through this “prism,”
